how do i make my 325e a stroker and cheap

That was the impression I was under. The extra 0.2L of displacement would raise the CR slightly assuming the crown shape and compression height were equal at tdc.

Mahle lists the sets pistons at 8.5.

Since they supplied BMW the m20 pistons, I tend to believe them.

I was under the impression that you could use the ETA pistons, rods, crank basically whole bottom end with the head swap from an I without the piston slap or any other problems besides a super low compression ratio?

Theres no issues. The powerband is a bit diffrent in stock form. You loose a bit of topend power. Falls off past 6200 but makes up with the super lowend/mid range power.

Did you read the whole 33 posts in this thread, or just reply to the first?

I may have skimmed through it ;)

seta = 8.50:1
327i = 8.43:1
b25 = 8.80:1
i pistons/e crank/rods 2mm off block = 9.5:1
(all with stock full head height)

The seta pistons have a larger dish in them than the i pistons guys. Yes, even though they appear to be domed the i pistons are -1.2cc's, haven't measured the seta pistons, but will eventually as I have a set.
